Using Spacecraft Signals to Measure Sulfur Species on Venus
Upcoming missions to Venus will seek trace amounts of sulfur-containing molecules that can help us study the planet’s sulfuric acid clouds and search for active volcanoes.

Astrobites reports on how stellar rotation is slowed by stellar winds via magnetic braking, with a special focus on stars cooler than the Sun.
Astronomers have seen an extraordinarily bright, long-lasting radio flare in the center of a nearby galaxy. Could this be evidence of a star being shredded by a supermassive black hole?
Researchers have discovered a potential companion to a star that exploded 8,000 years ago. Its characteristics raise interesting questions about which stars are able to donate enough material to trigger a supernova.
Astrobites reports on a new investigation of the Andromeda Galaxy’s gamma-ray emission that reveals it to be far different from originally thought.
All scientists love to label and classify the natural world, but brown dwarfs resist such artificial labels and can’t be cleanly categorized as either a star or as a planet. Now with JWST though, astronomers are getting their best look yet at these enigmatic worlds.
Astronomers pair data from a planet-hunting spacecraft and a stellar-position plotter to track down pulsations in a nearby star cluster.
Astrobites reports on what we might be getting wrong by assuming that slightly squished planets are instead perfectly round.
In rare cases, certain supernovae might produce high-energy neutrinos, allowing our neutrino detectors to track down exploding stars out to greater distances.
Some high-redshift galaxy candidates in JWST images are curiously point-like. New research investigates whether these sources might be supernovae instead.
New high-resolution three-dimensional simulations explore the nature of accretion onto supermassive black holes in elliptical galaxies.
When the next moonwalkers land near the lunar south pole, they’re going to need a map. With a possible Artemis III landing just a few years away, planetary scientists are hard at work trying to make one fit for spacesuit-clad geologists.
